ALFRED BULLOCK, OF NEW YORK, N. Y.

TABULATOR FOR TYPE-WRITERS.

Specification of Letters Patent.

Patented Apr. 15, 1913.

Application filed January 24. 1912. Serial No. 673.047.

To all whom it may concern Be it known that I. ALFRED BrLLocK a citizen of the United States, and resident of the borough of Brooklyn. county of Kings, city and State of New York. have invented certain new and useful Improvements in T abulators for Type-Writers. of which the following is a specification.

This device is intended for use with typewriters not provided with the more complicated and mechanical tabulating devices, and is constructed as a substitute scale to be applied in place of the ordinary scale usually provided to indicate the position of the carriage.

This tabulator does more than the ordinary mechanically operated device can do in that it tells at a glance the number of character spaces used. the number available for future use, the number of columns of figures of any denomination that may be placed upon a sheet as well as the starting and finishing point of each column, and much other information not here set forth.

The details of the construction and operation ofmy device will appear as the specification progresses.

The following is what I consider the best means of carrying out this invention.

The accompanying drawings form a part of this specification, in which:

At Figure 1, I have'shown a completed scale, and, F ig. 2 shows a modified form of pointer that may be used therewith. 4

Similar reference numerals indicate like parts in all the figures where they appear.

Referring to the drawing at 1, I have shown a plate upon which the scale and other characters are produced. This plateis provided with outwardly extending parts 2 and 3, each of which is provided with a perforation 4 arranged and adapted to accommodate screws by the means of which the scale is secured to the carriage of a typewriter. Each of the perforations 4 is somewhat elongated so as to allow the scale to be adjusted to the proper position before the screws are firmly secured. Adjacent to the upper edge of the plate 1, I have engraved a scale 5. subdivided into seventy equal parts and having each fifth part.

numerally indicated. Immediately below this scale I have arranged an additional series of numerals 6. advancing by units and in the reverse order from seventy to one. A short distance below the series of numerals 6 I have engraved a second series of numerals T, advancing in units from O to seventy.

Below this series of numerals 7 I have arranged five lines of figures, the first line 8, commences at space 7 and extends to the spaceTO and sets forth five-different times the characters for five columns of nine figures each with the proper decimal points and commas allowing -a space between each column of figures. The second line 9, commences with the space 6 and extends to the space 70 and sets forth six columns of, figures of eight characters each together with the proper points and spacesbetween each column. The third line sets forth seven columns of figures of seven characters each together with the proper points and spaces. The fourth column 11, sets forth eight columns of figures of six characters each together with the proper spaces and points, and the fifth and bottom line 12 sets forth 10 columns of figures of five characters each together with the proper points and space-z Arranged along one side of the columns of figures is a slot 13 provided with a plurality substituted for the indicating pointer with which a typewriter is provided. This pointer 19, which is secured in the position of and by the means provided to secure the ordinary pointer is provided with a knife-edge or hairline 20 resting adjacent to the scale 5 and the pointer is slightly bowed immediately below the knife-edge as shown at 21, so that the supporting standard for the knife-edge will be away from the indicator of the printing line. A right angle projection 22 serves to allow this pointer to be secured to the machine by the ordinary means. i

The operation of this device might be considered obvious from its construction but I will nevertheless describe it in detail. The scale 5 indicates the writing line and the number of spaces and the proper location of the characters is set forth on that scale. At 6, the number of spaces yet to be used is shown, in this scale the spaces are each numbered: commencing from right to left and advancing *by units. The scale'7 indicates. the number of spaces numbering each one and advancing from left to right. The scale i h '8 shows that five columns of figures each should commence and end and where each;

point should be: placed and each spaceale lowed. The scale 9 shows that five columns" of six places and two places of figures each decimal may be placedbetween 0. and.70.

be placed and each space a1- lowed. The scales 10, 11, and 12' accomplish for 5, 4t, and 3 places respectively and each is arranged t'o-accommodate two places decimal; ing that seven columns of five places each a and decimals may be placed between 0 and and points to divide the 70, scale 11' that eight columns of four places 12' that 10 columns arranged between 0 and with, suflicient allowance for spaces between the columns columns. If the op: erator be writing a series of figures based on the scale 8, the button 15 is placed so that the arrow 16 indicates this scale andit serves as a constant reminder in moving the carriage, that the pointer must be brought to the position necessary to bring each column in alinement. In this way the device serves Scale 10 show- 7 as anordinarytabulator egtcept that there are" no mechanical stops, the operator moving t lte'carr'iage to t-heproper position by and; i

I'have described this device and its opera- .tion in the way in which I have developed it and'observed it, though I anrsurc that modifications maybe made within the scope ofthe appende d claims without departing from the principle or sacrificing the advantages of this invention.

:1 Having carefully and fully described my invention what I claim and desire to secure by Letters Patent is This scale also shows where each C0ll1IIl D should commence and end, and where each point should 1.
